4 claims.

'This invention relates to certain novel improvements in door mountings and latching means therefor, and has. for its principalobject the provision of an improved construction of this character which will be highly eicient in Luse and economical'in manufacture.

" Among the several objects of this invention is the embodiment of a simple combination and arrangement of parts in the hinge structures of a door which will permit the door to be .opened from either of the Vside jambs of the door frame.

A still further object of the inventionis the I provision of a simple latching arrangement for latching the hinge latch operating means in a predetermined position to prevent the door from beingopened from both of the side jambs at the same time.

A still further object of the invention is the.

provision for latching detachable hinge leaves together .utilizing for that pur ose a latching arrangement which will not in erfere or cause resistance to the closing and opening of a door. Y

ther objects will will appear hereinafter. vThe invention consists in the novel combination and arrangement of parts to be hereinafter described and claimed.

The invention willk be best understood by ref- 'erence to the accompanying drawing showing the preferred form of construction, and in which:

Fig. 1 is a part sectional and elevational view of a door frame and a door showing our improved door mounting associated therewith;

Fig. 2 is a fragmentary sectional detail View of the same taken substantially .on line 2-2 of Fig. l;

Fig. 3 is a perspective View of Vone of the hinge structures embodyingy the inventionl showing the hinge plates thereof inl separated position; and

Figj4 is a rfragmentary perspective View of the door showing the invention lassociated there- With with certain parts of the invention in disconnected position.

Referring more vparticularly to the drawing, 10 indicates a frame structure having Va door opening 11 normally closed by a door 12. door 12 includes the frame structure 13, a back cover plate 14 and a front or face plate 15.

' The door 12 ismounted to theside jambs 16 by means of hinge structures 17 yconstructed in :a manner such as will permit the door to be opened from either of the side jambs. Each of these hinge structures is substantially the same in structure, and therefore the description with This reference to one will be applicable tothe other.

In this connection, each hinge structure includes a hinge plate 18 which yis attached to the side lamb by means of screw elements 19V orthei like. This hinge plate includes spaced Vknuckles 60 20 between which isarranged alpintle21; A hing plate is indicated at 22, and this hinge plate is connected -to the door frame 13 by means of suitable screw elements 23. This plate 22 is preferably. connected to the frame beneath the cover 65 plate 15 so that a bifurcated knuckle 24 preferably formed as a part of the plate 22 will be exposed from beneath the cover plate 15.` The'biiurcation 25 of this-,knuckle is adapted to accommodate thei v pintle21 when the door is in closed position. 70

Ahinge plate 22 provides a' guiding groove 26 in which is sldably mounted a latch bolt 27, the latch end 28 of which is adapted to be disposed to obstruct movement of the pintle f 21 from the bifurcation. 25.as best illustratedin 75 Fig.f2. A

Projecting,upwardlythrough a slot 29 formed in that part-of the plate 22 providing the groove 26 is one end portion 30 of a bell crank 31 pref- L erably pivotally connected to the plate 22 :as at 80 32.\ This end portion 30 operates in aV notch 33 formed inthe latch bolt 27. To the other end portion 34 of the bell crank 31 is connected as at 35 a link 36, and this link extends toward the '1 middle portion ofthe door l2 beneath the plate 85 15 andY has its opposite end portion connected to one end portion of an'arm 37, asat 38. .Connected to this arm 37, which is pivotally mounted as at 39 toa plate 40, is theend portion of a latchj ing bar 41 guided in its movementby means of 90 a guiding strap 42 Vconnected to the frame as at 43. Y i

Pivotally connected to the plate is a keeper plate 44 provided with a latch shoulder 45 'normally urged in latched position by means of a spring 46 rdisposed to engage the lowerend portion 47 of this keeper plate and mounted -in a f boss 48, said spring having its inner end portion connected to the boss 48 by inserting-the end portion thereof into an opening 49 formed in100 this boss. y

The lower `end portion of this keeper plate is urged inwardly against the action of the spring 46 by means of a pin 50 having a rounded striking head ,51 formed thereon'and-'adapted to pass 105 As will be apparent, the operation of the latch 110,

bolts of the hinge structures on one side of the door are substantially the same as those on the other side of the door, and in this connection there will be two latching bars disposed with their inner end portions in line for abutment, whereby when one latch bar has been moved inwardly, it will abut the other latch bar and consequently prevent movement of that latch bar, thus preventing operation of the latch bolts on the side of the door opposite the open edge, and

consequently prevent the door from falling .from'b its opening with respect to the door frame.

To complete the invention, an operating handle is indicated at 53, and this operating handle includes a bearing portion 54 adapted to be mounted between spaced ears 55 provided by a bracket.56, which bracket 56 is attached tothe plate 40 by means of attaching screws 57 adapted to. be threaded into spaced bosses 58 provided by this plate.

The bearing portion 54 has formed as a part thereofapin 59 which is adapted to nt into an .opening 60 formed in the arm 37, whereby-when .thehandle 53 is manipulated in an upward Adi- .rection, the arm.37`will be caused to ypivot with its inner endportionmoving in a downward di- Vrection so as to exert downward pull on the bell crankl in a direction to move the latch bolt 1.27. in `a direction to dispose 'the latch end 28 -from1atched engagement with the pintle. As this arm 37 .pivots in the direction indicated, the outer end. .portion thereof .-will move upwardly, and .when ,moved in Vits extreme upward position, the Akeeper plate 44 .will pivot by action of the 'spring soas to dispose the shoulder 45 under theouter end portion of the arm 37, and in this position the .handle .opposite to the one operated cannot be .operated because the .latchv arm il having moved -intoa position by the pivotal action of the arm I37.,.wi1l. abut the latch arm onthevother side of thev door and consequently. restrain operation of the latch moving means of the hinge structures on the side supporting the door for pivotalr movement.

:In closing thev door the latch plate 44 will-be struck by thehead A51 of. the pin 50,.-and this vaction will pivot the keeper plate against the action. of the spring46 to disposethe shoulder 45 from latched engagement with the outer end of the arm.37 so that this arm may be pivoted in a direction` to. again dispose the latchbolts 27 into latched position withthe pintle 21.

-Bythe provision of this pin 50 it is obvious Y that the latchbolts 27 will in no way interfere Withmovement of .thehinge plates into position tobe.connected together by these latch bolts, vand as a consequence movement between the :hinge plates willbe smooth and uninterrupted.

While we have illustrated and described the preferred form of construction for carrying/our inventioninto effect, this is capable of variation and .modification without departing from the Vspirit of the invention. We, therefore, do not wish 4to be limited to the precise details of construction set forth, but desire to avail ourselves .of such variations .and modications as come within the scope of the appended claims.
